AMD's $17 billion forecast comes with a cash-flow catch

Advanced Micro Devices gave investors the number they were looking for on Tuesday. After the market closed, the chipmaker reported third-quarter revenue of $13.38 billion, up 45% from a year earlier, and guided fourth-quarter sales to about $17 billion, plus or minus 3%. Even the bottom of that range, roughly $16.5 billion, sits above the $16.23 billion analysts had expected, according to the consensus figure cited by Phil Stock World. The shares had closed at $483.90 and traded around $520 after hours, a gain of about 7.5%.

The data center business did the heavy lifting. It brought in $8.55 billion, up 97% year over year and 27% from the second quarter, as the first MI450-series Instinct GPUs shipped alongside EPYC server processors. Data center now makes up 64% of AMD's sales. Management said the segment should grow about 50% sequentially in the fourth quarter. That works out to roughly $12.8 billion, or about three-quarters of the guided total. CEO Lisa Su also told analysts she now expects total revenue to grow more than 80% in 2027.

Past the headline, though, the quarter shows what an AI ramp costs a supplier before it pays off. Three items deserved more attention than they got on Tuesday night: cash, inventory, and the equity AMD has promised its biggest customers.

Profit on paper, cash in the warehouse

AMD reported non-GAAP operating income of $3.92 billion and non-GAAP net income of $3.47 billion. Operating cash flow was only $1.2 billion. After $648 million of capital spending, free cash flow came to $554 million, about 16 cents of free cash for every dollar of adjusted net income. Nine-month operating cash flow was $6.5 billion, which means the first half averaged roughly $2.7 billion a quarter; the third quarter was a sharp drop, not the norm.

Chief financial officer Jean Hu tied the weak free cash flow to heavier working-capital investment and continued capital spending to lock in equipment and capacity. Inventory rose about $3 billion in the quarter to $11.46 billion, up from $7.92 billion at the end of 2025. She said the stockpile was built "to fulfill our strong data center demand," and the guidance backs her up: AMD needs to ship more than $4 billion of extra data center product in the fourth quarter compared with the third. Su acknowledged that "demand is higher than supply" and said AMD has lined up wafers, substrates, advanced packaging and memory to support next year's growth. Still, inventory built ahead of a ramp is a bet that the ramp arrives on time. Borrowing is rising too. Total debt reached about $7.1 billion at the end of September, up from roughly $3.2 billion (including the current portion) at the end of 2025, after AMD raised about $4.7 billion in the quarter, largely through a $4.75 billion senior-notes sale in August. The cash-flow statement shows no open-market share repurchases in the quarter.

The warrant line

GAAP earnings were $1.46 a share, compared with the adjusted $2.09. The single largest reconciling item was a $1.1 billion non-cash charge, or 66 cents a share, for remeasuring warrants AMD has issued to "certain customers" — on its own larger than the 63-cent gap, which other adjustments partly offset. The release does not name the customers, but AMD has disclosed warrants of this kind tied to its two largest GPU deals, with OpenAI and Meta. Meta's warrant, disclosed in an 8-K filed in late February, covers up to 160 million AMD shares at a penny each. It vests in tranches as shipments build toward 6 gigawatts of Instinct capacity and as AMD's stock clears escalating price thresholds, the last of which is $600; Meta must also meet technical and commercial conditions, and the warrant runs until February 2031. Tom's Hardware reported at the time that the Meta deal mirrored AMD's October 2025 agreement with OpenAI, which also handed the customer the right to roughly 10% of the company.

The accounting has an odd feature: the better AMD's stock does, the larger the charge. Hu attributed the quarter's charge "primarily" to the higher share price and to changes in AMD's estimate of how likely the warrant conditions are to be met. AMD traded just under $200 when Meta signed and closed near $484 on Tuesday. At that price, Meta's full grant would be worth roughly $77 billion, though full vesting would also require the stock to reach $600. Put simply, part of what customers are paying for AMD's AI hardware comes back to them as AMD stock. Hu said AMD does not expect customer warrants to affect its fourth-quarter diluted share count, guided at about 1.67 billion including the expected closing of its deals for inference-chip developer Taalas and Fei-Fei Li's World Labs. In answer to a later question, she said warrant shares would add dilution only once their vesting and exercise conditions are met. That makes them invisible in near-term share counts, but any per-share valuation that ignores them is incomplete.

Margins are the next test

The growth is also coming at a slightly lower gross margin. AMD guided fourth-quarter non-GAAP gross margin to about 55%, down from 56%, even though revenue is supposed to rise 27% from the third quarter. The cause is mix. Hu described the data center AI ramp as a little dilutive to the corporate average, and the bear case laid out by 24/7 Wall St. before the report was that lower-margin Helios racks could weigh on the mix even if revenue beat. Meanwhile the consumer businesses are shrinking. Gaming fell 40% year over year to $773 million, and management guided the combined client and gaming segment down more than 20% sequentially, with Su saying higher memory and component costs had weighed on demand. Su said "other component costs are also seeing some inflationary pressures" and that AMD is working with customers to share them. Asked about quarterly margins in 2027, Hu said she does not yet have that visibility.

Even so, the data center segment is getting more profitable as it scales. Its operating income reached $2.9 billion, up 168% from a year earlier, for a margin of about 34%, compared with about 25% a year ago.

What the market is pricing

The bullish case has support. Su said lead customers including Anthropic, Meta, Microsoft, OpenAI and Oracle have brought their first Helios racks online, a broad set of customers for a platform that only began shipping in volume this quarter. OpenAI also picked AMD's Turin EPYC chips as the host processors for its first custom accelerator platforms. The 2027 outlook topped the roughly 77% growth analysts had expected, according to Reuters figures cited by Phil Stock World. Su also stressed that the ramps of the MI450 series, Helios and the next Venice server CPUs are "still early."

Much of that was already in the price. Before the after-hours jump, AMD traded at about 176 times trailing earnings, according to 24/7 Wall St., whose live coverage also noted that the shares had slid more than 20% over the previous month and pointed to Broadcom's below-expectations AI forecast as a warning sign. Analysts' 2027 earnings-per-share estimates range from $9.60 to $23.66, a spread that shows how little agreement there is on what the ramp will earn. When AMD reports the fourth quarter, three things will matter alongside revenue: whether inventory turns back into cash, whether borrowing keeps climbing, and whether data center margins hold as Helios volumes rise. A $17 billion quarter would settle the revenue question. It would not show whether AMD is winning that revenue on terms that work for its shareholders.
